I think the reason why stability fails after 400 FSB is because its changing you're Memory speed as well. So increasing the Multiplier will be the logical solution, Unless you want to play around with you're ram settings to get a higher FSB, Such as loosening the timings and increasing memory voltage.

Just do it step by step and you'll soon be there! thumb.gif

Thanks mate, working on it, I think I need to up my FSB overvoltage a bit (VTT) as I have crashed 4x already. As soon as I added a little bit (+0.05) I was able to run Prime95 but with errors... I think I am in the right path... again! haha.

If so I will consider one for my Q9650! I max out at 4.2GHz at about 1.41v under full Prime 95 load. hottest core hit 78C. Maybe with that H70 I could push my CPU further. Because my P5Q-E can handle up tp 480FSB +. That would be 480FSB x9 = 4320Mhz. Maybe not worth the cost of the H70, but I can always take that H70 with me for my next upgrade Right now I'm using a Thermaltake Extreme Ultra with a 120mm 1200rpm - 1700rpm at full load..
Yes mate! Well at least here I can... I need to take into consideration that the case is open and temperature is 17 Celsius outside (which is probably the temps you get during summer in Norway right? ).

I'll post a pic as soon as I can with the results, I am currently trying 3.42Ghz, still crashing... gah!

I've decided that I don't want to pass 1.55 Vcore. That will be my limiting factor as I don't want to fry this system too soon. I've done some reading on limits and 1.55V seems to be quite reasonable, and no matter what your cooling is, eventually it's just too much voltage.

3.42Ghz had some errors during prime95 but it didn't crash. I think I just need to tweak a bit more in other areas. I'll aim for a final 3.6Ghz with a maximum 1.55V. If I can't achieve that then it will be 3.42Ghz, which in my opinion it's pretty good.

What V-core do you have at idle and load for 3.4GHz +?

1.54 @ 3.6Ghz.

I have been trying to up the NB/MCH but no matter what I do it loads Windows 7 and as soon as I start to open programs it freezes and then blue screen.

I'm stuck.

Now same thing as before but VCore value in idle @ 3.6Ghz went down to 1.52V. then it crashed.

Should I disable Loadline calibration?

If you disable you have to compensate for the Vdroop. You'll end up with a higher V-core at idle and lighter load.

I've actually it is better to have LLC enabled and just increase V-core until it has enough for Idle/Light load...

Yes, it's on "Auto", I haven't touched it.

I've decided to pull back on the volts to see what happens... It's crashing earlier than before, from 1.50V up to 1.55V. It just looks like I am missing on something. I don't believe that this CPU/mobo need more than 1.58V to run at 3.6Ghz.

Btw, my RAM seems to be locked at 1333Mhz in the BIOS and it seems to be linked with the FSB.

Is there a way to put it back to 1600Mhz? Or should I jsut mess around with the timings once I get my CPU OC stable?

Ok, maybe I'll need to compromise Vcore vs Temp.

I was running it ok on Prime with Vcore1.65V set in the BIOS.

CPUID shows Minimum 1.60V, maximum 1.66V and it is operating with 1.62 at 100% CPU load.

Temperatures reaching 60 Celsius maximum.

It crashed at the 4th run in Prime95, 5 minutes after starting. This has been the longest I've achieve while @ 3.6Ghz.

Unfortunately it just seems to be wanting more power and I am not sure if there is anything else I can do to keep it stable... Maybe I have just reached the CPU's limit and I just have to accept that this one isn't very flexible...

Any suggestions?
